He became a half-human, half-demon creature (second appearance was when the party got the Earth Elemental Pearl).

According to your source (the Chinese wiki page), Luo Ru Lie's first appearance in the game was when the party was getting the Earth Elemental Pearl. However, in the drama, that was his second (with the first being the vampire arc, and the third being Mao Shan's exchange; both of which didn't exist in the game). So depending on what you're asking... there's the answer lol.

So I assume the whole end part was made up too, with the Fire Demon King and the other demon (who was in Suo Yao Ta) fighting at the end.. Random question- since Jing Tian took the fire pearl, how come the Fire Demon lady still looks young? I thought she needed those special soup to keep her skin nice XD
